European Standard IP55 waterproof and dustproof design.
Large-scale engineering and construction unit of the relatively poor working environment, noise, dust, using walkie-talkie radio from time to time due to the dirty work, or could not hear the voice of the inconvenience. DH288 specifically tailored for the construction unit, excellent waterproof and dustproof capabilities to be effective against dust and water into the body, to avoid damage to the machine to extend the life of the machine, optimizing the use of the machine results
High / Low Power Conversion
Power of each channel can be set by the corresponding function keys (high / low power button) to adjust, when the communication range is small, low power can be used to save battery power.
Monitor function
Press MONI key, you can monitor the activities of the current channel, the function receives a weak signal utmost advantage.
Automatic power saving feature
Without receiving signals or no operation, the transceiver will automatically enter power-saving mode, reducing power consumption, thereby extending battery life.
Low battery alarm
Battery charger automatically alert the user.
Busy channel lock
This feature prevents unauthorized users machine receives the signal and sends a signal to the busy channel to keep the channel clean and free from interference.
Time-out timer (TOT)
This function is used to prevent the prolonged occupation of a single radio channel. Each radio transmitter timer limits the time, so that can save the battery, reducing channel congestion level, but also to avoid inadvertently takes the phenomenon of the channel.
Loss Prevention wear, reliable design
Surface shell with PC fire prevention material, even in high temperature deformation is not the case, do not fade, with high wear resistance and impact strength, suitable for various harsh environment applications.
DTMF software codec
32-bit ARM chip, stable performance, excellent computing power greatly improved the su
